Acute Liver Failure (ALF) is a rare but potentially devastating process that often leads to urgent liver transplantation when it is believed that liver regeneration is unlikely [1], [2], [3]. In infants and children, inherited disorders affecting the liver are more likely to play a role in fulminant hepatic failure than in adults. Clusters of acute hepatitis in kids—many resulting in liver failure—in Europe and the United States are triggering investigations from the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), as the illnesses appear to be linked to infections with adenoviruses. A major challenge is to quickly determine the etiology and initiate appropriate . Toxins and drugs are a frequent cause of ALF in children.

The rarity of the disease, along with its severity and heterogeneity, presents unique clinical challenges to the physicians providing care for pediatric patients with acute liver failure. "Acute liver failure" (ALF) and "fulminant liver failure" are terms used interchangeably to describe severe and sudden onset of liver cell dysfunction leading on to synthetic and detoxification failure across all age groups. It is vital that children with ALF receive immediate care.
